SASH-FASTENER.

Specification of Letters Patent.

Patented Nov. 27,1906.

Application fil d Ianuary 31, 1906. Serial No. 298,865.

To all whom it may concern:

Be it known that I, NELs J OHNSON, a citizen of the United States,'residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented a new and useful SashFastener, of which the following is a specification.

This invention relates to sash-fasteners, and has for its object to provide an improved 1o device of this character which is complete in itself and capable of being applied to the upper sash for engagement with the lower sash, so as to lock the two sashes, 1t bemg particularly designed to arrange the device so as to r 5 permit a limited opening of the sashes for the purpose of ventilation.

It is furthermore designed to provide for conveniently locking the bolt of the fastener projected and also retracted and to enable the convenient release of the bolt from either of its locked positions.

WVith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be here- 2 5 inafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made 0 within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a longitudinal sectional view taken through the meeting- 5 rails of upper and lower sashes with the fastener of the present invention applied thereto. Fig. 2 is a perspective view of the fastener removed from the sash. Fig. 3 is a front elevation thereof. Fig. 4 is a sectional view of the fastener with the bolt retracted.

Similar numerals of reference designate corresponding parts in all of the figures of the drawings.

The present fastener includes a face-plate 5 1, of suitable proportions, preferably oblong in shape, and pierced at opposite ends by countersunk openings 2 for the reception of screws or other fastenings to secure the device in place. At one side of the middle of the plate the latter is pierced by a bolt-open- 5 5 lar case 5 extends rearwardly from the open ing 3 and is provided at one side with a longitudinal slot 6. Vvorking in the case and the bolt-opening is a bolt 7, having a pin or projection 8, working in the slot 6, so as to prevent rotation of the bolt and limit its outward movement. This bolt is yieldingly held at its forward limit by a helical spring 9, housed within the case and bearing in opposite directions against the back thereof and the rear end of the bolt. Opposite the flange 4 there is a latch. 10,'mounted to rotate upon a stud or pin 11, loosely piercing the latchand carried by the plate, the outer end of the latch being provided with an annular flange 12, which is designed to take into a seat or notch 13, formed transversely in the under side of the forward portion ofthe bolt, as in Fig. 1, so as to lock the bolt at its forward limit. A portion of this flange is removed, so as to form a concaved notch or seat 14, which when turned into alinement with the notch 13 engages the lower side of the bolt and perm its of the latter being pushed into the case.

In practice the present fastener is applied to one of the stiles of an upper windowsashsuch, for instance, as shown at 15the plate 1 being let in flush with the inner face of the stile and the case 5 being received within a socket 16. When the bolt is at its forward limit, it overhangs the meeting-rail of the lower sash 17, thereby to lock the two sashes against further opening movements. By preference a metallic plate 18 is secured to the top of the meeting-rail of the lower sash, so as to take the wear of the bolt 17. To hold the bolt against being retracted, the latch is turned to bring its flange 12 into the notch or seat13 in the bottom of the bolt, whereupon the latter is locked against movement in either direction. In view of the fact that the stiles of window-frames are set back from the meeting edges of the meeting-rails there is sufficient space between the stile of the upper sash and the meeting rail of the lower sash to accommodate the latch 10. To release the sashes, the latch is turned into the position shown in Fig. 3, so as to bring its notch 14 into alinement with the notch or seat 18 of the bolt, whereupon the bolt and the latch are out of engagement and the bolt may be forced-rearwardly into the case out of the path of the meeting-rail of the lower sash. To hold the bolt retracted, the tumbler is turned so as to bring its flange across sashes may be moved to their full limits.

The purpose of the flange 4 is to brace the forward end portion of the bolt against up-v ward strain thereon by reason of its engagement with the meetingrail of the lower sash.

Having thus described the invention, what is claimed is- 1. A sash-fastener comprising an attaching-plate, a bolt working through the plate, a substantially semicylindrical flange carried by the plate and embracing the bolt-opening to brace the bolt, and a latch carried by the plate oppositethe flange and in cooperative relation with the bolt.

2. A sashfastener comprising an attachingplate, a bolt working through the plate and provided in one side with a transverse recess, and a flanged latch mounted upon the plate and capable of being turned to bring its flange into the recess of the bolt to lock the latter, the flange of the disk having an edge notch to receive the bolt and permit endwise movement thereof.

3. A sash-fastener comprising an attaching-plate, a bolt working therethrough and provided with a transverse recess, and a flanged latch-disk rotatably mounted upon the plate to have its flange engage the recess and lock the bolt, the flange of the disk thereof, and said flange capable of engaging the outer end of the bolt when retracted to lock the same.

4. A sash-fastener comprising an attaching-plate having a bolt-opening, a case carried by the plate in alinement with the opening and provided with a longitudinal slot, a bolt working in the case and through the opening and provided in its forward portion with a transverse recess, a pin carried by the bolt and working in the slot of the case, a spring housed in the case and bearing against the bolt, and a rotatable disk carried by the plate and provided with a peripheral flange to engage the recess of the bolt and lock the latter, the flange of the tumbler having an edge notch to receive the bolt and permit endwise movement thereof,

and said flange capable of being engaged across the outer end of the bolt to hold the same retracted.

In testimony that I claim the foregoing as my own I have hereto afliXed my signature in the presence of two witnesses.
